To all whom it may concern:

Be it known that I, COLU BUS T. C oornn, a citizen of the United States, resldmg at Anderson, in the county of Anderson and State of South Carolina, have invented new and useful Improvements in Warper Attachments, of which the following 1s a speclfication.

This application is refiled for abandoned 1 application No. 555,765, filed Apr. 16, 1910. This invention relates to warpers and has for its principal object to provide means whereby the loose lint from the threads w1ll be prevented from settling on the drop wires, combs, and drop wire bars of the warper so as to materially increase the efiiciency of the warper and insure a production of a perfect product from the warper.

A further object of the invention is the provision of an extremely simple, efiicient and practical device of the character referred to in the nature of a fan so arranged as to distribute a blast of air over the parts on which the lint or short fibers from the 95 threads usually settle so as to keep the said parts at all times free from settlings Another object of the invention is to provide a blast device of such a design that it can be used as an attachment for machines now in use without requiring any alteration therein, the fan being driven by one of the rotating arts of the warper.

With t ese objects in view and others as will appear as the description proceeds, the invention comprises the various novel features of construction and arrangement of parts which will be more fully described hereinafter and set forth with particularity in the claims appended hereto.

In the accompanying drawing, which illustrates an embodiment of the invention Figure 1 is a front elevation of the attachment applied to the end of a warper. Figure 2 is a side view of Figure 1. Figure 3 is a plan view of the air distributing means a Figure 4 is an enlarged detail view in elevation of the air distributing means.

Similar reference characters are employed to designate corresponding parts throughout the several views.

'" desi The difliculties in the operation of warpers ed to be overcome by the present invention will be first described before entering into a detail description of the invention. A beam warper carries anywhere from 300 to 500 ends of yarn, and each of these threads passes through a separate drop-wire, and dent in the comb. These threads pass through these wires and dents at a rate of sixty yards per minute, and there is an enormous amount of short fibres or lint chafiin off the threads settling on the wires and bars, and also the comb boxes, especially between the front comb box and front dropwire bars which form a groove or trough about, one and one-half inches deep and sixty inches long. In this groove or trough is where the principal part of the trouble is with warpers catchmg lint and other foreign substance, although the lint settling on drop wires causes them to choke up and not fall when a thread breaks. These wires are about two inches long and one sixteenth in diameter, and are set at an angle of about sixty degrees. These wires work automatically and when they are free from lint will stop the machine when an end breaks down.

'If the machine fails to stop, as is usually the case in many instances, then the work is very badly damaged and causes imperfect goods' when it reaches the looms. The threads on warpers pass directly over the grooves mentioned above, and the chafiing 'of the yarn soon causes the groove to fill up until it comes in contactwith the yarn. Just as soon as one of the ends touches this lint, it causes the whole amount in this groove to link together, and

as it comes in contact with the yarn, will cause fully nine-tenths of the threads to carry a large bunch of loose lint. After leaving the warpers, the yarn goes .to" the slasher room, and the large bunches of loose lint is run through the sizing kettles which gives it a firm hold on the good work and when it reaches the looms it usually causes a number of threads on each side to lap up and damage the goods very materially.

Referring to thedrawin A designates a rotary fan or blower, whic is mounted on v I one end 1 of the frame of a beam warper,

the fan consisting of a wheel 2 rotatabl mounted in a casing 3 that is provided wit a bracket 4 bolted to the frame 1 at the belt end thereof. The wheel is mounted on a shaft 5, which is provided with a ulley 6 around which the belt 7 passes. his belt also passes around a large pulley 8 on the top cone shaft of the warper, which shaft is driven by gearing 9 from the driving shaft 10 on which the usual belt pulleys 11 are mounted. The belt 7 crosses at a point adjacent the smaller pulley 6 so that a maximum area of contact will be obtained between the ulley and belt to thus avoid slipping, it being understood that the speed of rotation of the fan is considerable since the cone shaft makes about four hundred and twenty revolutions per minute.

'l ne fan supplies air to a distributing device B arranged at the to of the end portion of the frame 1 and t is device is connected by a duct 12 with the fan casing so that air will be forced by the fan wheel from the duct and distributed by the device B over those parts of the warper that are liable to be clogged by lint or fiber chaifed off from the fast traveling threads. The device B consists of an elbow 13 arranged on the upper end of the duct 12 and so positioned that the arm of the elbow that discharges the air will be disposed horizontally at the top of the machine, the said elbow being supported by a bracket 14 which is secured to the upper part of the frame 1. As the area to be cleaned or kept free from lint or fiber is about twenty inches wide and sixty inches long, it is necessary to provide an air deflecting means so that the blast delivered from the fan will be effectively distributed to play on the drop wires, combs, drop wire bars. For this purpose a vane 15 is arranged directly in front of the discharge nozzle or elbow 13 and is adapted to have an oscillatory or rocking movement so as to deflect the air over the desired area. The vane is supported on a vertical rock shaft 16 journaled in arms 17 on the bracket 14 and this shaft has a crank arm 18 that is connected by a link 19 with a crank arm 20 which is secured to the stop-motion rod 21 of the warper. Hence as the rod 21 rocks the arm 20 will swing back and forth and cause the fan-carrying shaft to rock and in this manner the air will be regularly distributed over the parts to be cleaned.

From the foregoing description taken in connection with the accompanying drawings, the advantages of the construction and the method of operation will be readily apparent to those skilled in the art to which the invention relates, and while I have described the principle of operation of the invention, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and that such changes may be made when desired as are within the scope of the claims.

Having described the invention, I claim 1. The combination of a warper including an element having a rotary back and forth movement, with a blast producing device inoludin a discharge nozzle arranged to direct a last against the drop wires and adjacent parts of the warper, a device mounted on the warper and arranged in the blast for distributing the same over a wide area of the warper, and an operating connection between the said element and last mentioned device for operating the latter.

2. The combination of a warper, a blast producing device mounted thereon, means for driving the device by a moving part of the warper, said device including discharging means arranged adjacent the drop wires and adjacent parts of the warper, and a distributing means disposed in cooperative relation with the dicharging means and operated by a moving part of the warper for distributing the blast over the drop wires and adjacent parts to be cleaned.

3. The combination of a warper, means for driving the fan by a moving part of the warper, an air duct connected with the fan, a nozzle on the duct arranged to direct a blast of air against the drop wires and adjacent parts of the warper, and a vane mounted in front of the nozzle and automatically actuated to distribute the air over the parts to be cleaned.

4. The combination of a warper including a stop-motion rod, a'blast producing device having a nozzle arranged to direct air on the warper, and a deflector arranged in cooperative relation with the said device and operatively connected with the said rod to distribute the blast over difi'erent parts of the machine.

5. The combination of a warper including a cone shaft and a stop-motion rod, with a blast-producing device including a fan, driving means between the cone shaft and fan, and means actuated by the stop-motion rod to distribute the air delivered by the fan over the drop wires, combs and dropwire 7. In a warper, the combination of a cone shaft, means for driving the same, a fan mounted on the frame of the warper, means for driving the fan by the cone shaft, a duct connected with the fan, a nozzle on the duct.

over those portions of the warper liable to be obstructed by lint, means for mounting the vane on the frame of the warper, a stop motion rod, and means for connecting the rod with the vane for actuating the latter.

8. In a warper, the combination of a device mounted to discharge a blast of air against the drop wires and adjacent parts of the warper, a vane disposed in front of the device to distribute the air over a wide area, a rock shaft on which the vane is mounted,
